An engine air inlet system comprises an air inlet pipe (8), an air inlet manifold (6), and an auxiliary air inlet assembly (4) disposed on the air inlet pipe (8) and located before the air inlet manifold (6) of an engine. The auxiliary air inlet assembly (4) comprises an auxiliary air inlet channel, an auxiliary air outlet channel (21), and a central channel (39). Air enters through the auxiliary air inlet channel, comes out from the auxiliary air outlet channel (21) and enters the central channel (39), so as to be mixed with air from the air inlet pipe (8). The present invention further relates to an engine air inlet system, comprising an electronic booster (4'') located before the air inlet manifold (6) of an engine. An air flow enters from an air inlet (4241''), flows out from an air outlet (4242''), is mixed with air that flows through the air inlet pipe (8), and then is inhaled into a cylinder of the engine. The present invention further relates to engines respectively comprising two engine air inlet systems. These air inlet systems and engines can effectively reduce discharge, reduce oil consumption, improve engine efficiency, improve a low-speed torque feature of the engines, and improve a low temperature cold start effect of the engines. |
